7 Deadly Sins

Meet the most wrathful, prideful, gluttonous, lustful, greedy, slothful and envious members of the animal kingdom. Gluttonous ornate horned frogs will eat anything in their path -- even their own kind -- before ultimately choking to death. And hell hath no fury like a wrathful hippo whose territory has just been encroached. These docile-looking animals turn into powerful jaws of death if disturbed -- they can even snap a crocodile in half in one bite.
